About SAML vs RADIUS User Experience.
Some integrations interoperate with Okta through either RADIUS or SAMLAn acronym for Security Assertion Markup Language, SAML is an XML-based standard for exchanging authentication and authorization data between an identity provider (IdP) and a service provider (SP). The SAML standard addresses issues unique to the single sign-on (SSO) solution, and defines three roles: the end user, the IdP, and the SP.
Here's how SAML works through Okta:
SP-initiated flow: the end user requests (principally through a browser) a service from the SP. The SP requests and obtains an identity assertion from the IdP (in this case, Okta). On the basis of this assertion, the SP can decide whether or not to authorize or authenticate the service for the end user.
IdP-initiated flow: with Okta as the IdP, an end user goes to the Okta browser and clicks on an app, sending a SAMLResponse to the configured SP. A session is established with the SP, and the end user is authenticated. 2.0.

There are several advantages to using SAML integrations when available.
SAML provides a rich, intuitive and consistent login experience. RADIUS interacts with a text-based challenge with inconsistent formatting. Using SAML can reduce user training and support requirements and the consistent sign in experience with SAML makes users less susceptible to phishing attempts.
SAML integrations provide more security as credentials are exposed to fewer parties.
SAML integrations run with a simplified infrastructure. The do not require running on-premise agents and require little maintenance. The user agentA software agent is a lightweight program that runs as a service outside of Okta. It is typically installed behind a firewall and allows Okta to tunnel communication between an on-premises service and Okta's cloud service. Okta employs several agent types: Active Directory, LDAP, RADIUS, RSA, Active Directory Password Sync, and IWA. For example, users can install multiple Active Directory agents to ensure that the integration is robust and highly available across geographic locations. (web browser, VPN clientEssentially, a client is anything that talks to the Okta service. Within the traditional client-server model, Okta is the server. The client might be an agent, an Okta mobile app, or a browser plugin. , etc.) is used to transmit messages in a secure manor; therefore, there is no need for the service provider (firewall or application server) to connect to Okta. Federation is established through a one-time exchange of SAML metadata. This one-time setup establishes trust for ongoing transactions.
Okta SAML integrations are very robust and include adaptive MFA and provisioning.
The SAML appAn abbreviation of application. Essentially, it is a web-based site used to perform any number of specific tasks, and requires authentication from end users by signing in. for Cisco ASA is titled Cisco ASA VPN (SAML).
